SN74LVC1G18YEPR

Overview

The SN74LVC1G18YEPR is a single-channel, noninverting demultiplexer from the Texas Instruments LVC logic family. It routes data from input A to either output Y0 or Y1 based on the state of the select (S) input. The device features three-state outputs that enter a high-impedance state when deselected. It operates within a supply voltage range of 1.65 V to 5.5 V and supports inputs accepting voltages up to 5.5 V. The maximum propagation delay is 3.4 ns at 3.3 V. It utilizes a NanoStar WCSP package with large bumps.

Feature Summary

• Routes a single data input to one of two outputs based on a select signal
• Outputs enter a high-impedance state when not selected
• Supports partial-power-down mode via Ioff circuitry to prevent backflow current
• Inputs accept voltages up to 5.5 V for level translation compatibility

Applications

• Portable consumer electronics requiring low power consumption
• Battery-powered systems utilizing partial-power-down capabilities
• Signal routing in embedded control circuits
• Level shifting between 1.8-V and 5.5-V domains

Procurement Notes

Verify the specific ordering suffix YEPR corresponds to the NanoStar WCSP package with large bumps before procurement. Confirm the component status is appropriate for the design lifecycle, as availability may vary. Ensure the operating temperature range meets the application requirements. Cross-reference the datasheet revision date to confirm parameter accuracy.

Selection Notes

Select this component when a compact, single-channel demultiplexer with three-state outputs is required. The wide supply voltage range allows operation across various digital logic families. The low static current makes it suitable for battery-operated devices. Verify that the package dimensions fit the available PCB real estate constraints.

Part Context

This device belongs to the SN74LVC1G series of single-gate logic components manufactured by Texas Instruments. The LVC family is designed for low-voltage applications while maintaining compatibility with standard CMOS levels. The specific YEPR suffix indicates the use of the NanoStar packaging technology.

Replacement Considerations

SN74LVC1G18YZPR shares identical electrical specifications but uses the NanoFree package.
